Cylinder heating

■ To achieve the heating of a consumer
within a specific range, the sensors for
functions "Thermost. 3" and "Ther-
most. 4" (in the delivered condition S5
and S6) are required. These may be
switched to sensors that are already in
use (see page 161).
■ Reference parameters are the start
temperature "Th3on" and the stop
temperature "Th3off".
■ Relay R6 on:
When "Th3on" is not reached at either
sensor.
■ Relay R6 off:
When "Th3off" is exceeded at both
sensors.
■ In addition "Timer switch 2" (see
page 159) can be activated for this
function.
